Clan Name: Arkarni (pronounced Ar-carn-Eye)
Physical Appearance: As their primary species...For their primary form. However, they tend to have elongated top incisor teeth. Even in species that dont have those teeth.
Abilities, traits: While the Arkarni are a Clan of Vampire, they are very, very, VERY often mistaken for a horrifying breed of Werecreature. Indeed, the common name of the Arkarni is...The Werespider. Arkani possess the ability to shift their form from the normal parent race to two others-A massive spider that size of a car or truck, or a swarm of thousands of small spiders. Arkarni are proficient in mental-based magic, most specifically magic that horrifies and spreads insanity in general to their foes, though they are fairly good at magic that alters memories and personality. In fact, they almost always have a constant 'field'(for lack of a better term) around them that causes a feeling of unease and potentially fear when the Arkarni is present(it is of note this 'field' flares in power while they are in their 'giant spider' form and briefly becomes ridiculously strong when they turn into the swarm or reconstitute themselves, though that does fade quickly back to normal). A second proficiency Arkarni have is Illusion-based magic, which they often use to supplement their fear and insanity magic, allowing them to much more easily and drastically harm their opponent's psyche.
As far as weaknesses go, Arkarni are Vampires, so they're very weak to sunlight. In Arkarni, the light of Day causes their flesh to liquify and bubble. It is a slow, agonizing death. Even if the damage done is not lethal its almost always crippling, and for a unknown reason the damage done is exceptionally hard to heal using magic, even that of another. Fortunately, it is not ultraviolet light or any wavelength specifically. This weakness applies only to the natural light of a natural sun; manufactured sunlight, whether by technological or magical means, actually have no effect. A second weakness they possess is the cold. While the are actually Undead, unlike most Undead, Arkarni are more strongly tied to warmth than the chill of death, and they can even die of cold if they cannot get enough warmth. Lastly, in all forms a Arkarni possesses the same consciousness. This may not sound like a difficulty at first...But when was the last time you possessed the body of a eight-legged creature with eight eyes, a abdomen, and a completely different center of balance and method of motion? And thats just for the giant spider form, let alone having the thousands of tiny-spider bodies. Its very disorientating and it usually takes months to just get the giant spider form down, then years to master moving as a swarm.
Oh yeah and like Valshiek, Arkarni need to drink blood to 'survive'. Their curse feeds off the sacred property in it to sustain itself, if they stop drinking fresh blood they will die as their body just stops being undead(and into true death, they dont become alive again). They can sustain themselves on blood packs if need be, but this only prolongs their unlifespan. They'll eventually need to drink fresh blood.
Finally. There is only one Grand Arkarni known to exist, and the Arkarni as a whole practically worship her. She is the progenitor of their Clan and has many powers other Arkarni simply lack, though the details on her are sketchy at best to any besides those in the Coven she directly leads. Just about the only concrete detail is that she has some form of telepathy to any and all Arkarni that they cannot block out. Because she is the only Grand Arkarni, it is unknown how one ascends to that level of power. Some even think its literally impossible, that she is the only Grand Arkarni because she simply made the curse that way, to remain the strongest of her kind.
Typical Lifespan: Indefinite, as they can stave off age(like most Vampires can in some way shape or form). However, they typically dont live that long, given that most Empires they begin to spread into hate and fear them, and even other Vampires mistrust them at best.
Public or private?: Private. If you actually WANT one, all I ask is you work it out with me(although I honestly doubt anyone will want a Arkarni enough to request a char other than me)
Other information: Arkarni are very alien, even to those of the race they used to be. A lone Arkarni will typically seek out a existing Coven of others of his or her Clan, even when they dont know what they are(let alone that there are others of them). They can even reject joining entirely, they're just drawn to these Covens; some have turned this into a advantage, becoming Hunters and Slayers and using their innate 'Coven-seeking' to find and slay Arkarni Covens until they cant feel any more groupings of Arkarni(at which point they typically kill themselves). As well, the curse tends to shift and manipulate the personality of the Arkarni; they become secretive and manipulative very quickly, and their thought patterns can at times become very, very alien. Arkarni have their reputation amongst other Vampires for a reason after all. They tend to live amongst each other and shun those who aren't part of the Coven or Clan(as in, they'll act friendly towards either Arkarni and members of their Coven, but will otherwise shun everything else).
Aaaaaand I think that'll be it for these little guys. Small request this time, trying to get my brain working so I can finish my two Vampires Im still working on and because I liked the idea in general.
Edit:Oh also if the request just seems to be mostly rambling drivil its because Im requesting it at like 6-7 AM, just lemme know if anything doesn't make sense and I'll try to type up a sane explanation when Im fully awake that should be better.
